The average guy can replace the trigger spring and adjust it for about $20 for the spring kit and shipping , that would get you down to the 2lb range after that I'd just buy one , I like Riflebasix triggers for the money , they make several modles that range from heavier 1.5-4lb to light 2-6oz units ,they run around $100 for the light weight target models , but they are well worth it.
